Be it known that I, CHARLES F. EnIQKsON, a subject of the King of Sweden, residlng at Brooklymin the county of Kings and State ofNew York, have invent-ednew and useful Improvements in Air and Gas Mixers for Internal-Combustion Engines, of which the following is a specification. y This invention relates to air and gas mixers for internal combustion engines, the object being to provide a simple and eifec- A tive construction ofmixing device which may be inserted between'tl1e outlet of the carbureter and intake of the "engine or at any suitable point in the charge feed pipe, and which will operate tothoroughly admit. the air and gas Without choking the feed or' imposing any resistance to the free flow ofthe. charge-to'the engine. "The inve'i'iti'on consists of the .features of construction, combination and arrangement of parts, hereinafter fully describedgand claimed, reference being bad to the accompanying drawings, in Which Figure 1 isa side view, showing my im-. proved mixer-inserted for use between a carbureter and engine. Fig, 2 is a horizon tal transverse. section on the line 2+2 of Fig.1 1. Fig. 3 is avertical transverse section on the line 3-'3 of Fig. 2. Fig. 42 is a side view of the spider or fan supporting framedetached. Fig. 5 is a similar view of the body of the tan; omittingthe blades and bear-in ring. Fig. 6 is a viewsimilar to 2; s wing a modified form of 'mixer. Fig. 'Z'is a-section on the line 7-7of Fig. 6. Fig. 8 is "a section'taken substantially on theline 8.8 oitFig. 9, showing another modified form of mixer. Fig. 9 is a sec tion on the line 9-9 of Fig. 8. Fig. 10 is'a side view of the spider shown in Figs. 8

- and 9 prior to application. Eig. 11' is a detail view of the frame of the fan shown in Figs. 8 and 9, omitting the blades.

Referring to the drawings, 1 designates. the intake of an internal combustion engine, and 2 the outlet of a carburetor, Wliich parts are provided withthe usual perforated bolt ing flanges 3 for the passage of bolts'ito unite v entioii'is designed. to be interposed in said;

, conductor between said intake and outlet,

and comprises a casing A. formed .of two sections 5 and G -of substantially the same size and shape externally and provided with perforated flanges 7 'for the passage of the bolts i to secure said casing in position.' The inner portions of the casing sections are internally threaded, as at 8, for cou:

pling. engagement With the externally threaded outer or frame ring 9 of a spider or skeleton support arranged within the casin whereby said sections are detachably In addition to said ring the spider includes a central axle or bearing member formed of two spaced sections'lO and 11 having annular flanges 11' at their outer ends and cone surfaces 12 at their inner ends, said axle sections being connected with each other by a bolt or screw 13 and with the'ring 9 by a series of radial spokes or. arms 14:. I r I The spokes of -arms 14 are bail or-loo shaped and arranged obliquely transverse .y of the hub and ring. They are preferably forr ned of wirejand" serve as fixed heatersor cutters each embodying a pair of filamentsor slender strands to, subdivide or break up the charge minture iiito a plurality ,of streams 'on its passage through the casing.-

In the present instance, I have shown the series of heaters formed from a single piece of'wire threaded through transverse openings 15 in the ring 9 and openings 16 in the flanges 11' of the axle sections, but they may be independently formed and fixed at their ends v to" the axle sections in any pre ferred manner.

.A revoluble hub 17 surrounding the conefpoi't'iofis of the against lateral displacement Suitably secured within said hub'is-a' bearing ring'lB having cups 19 cotiperatiiiglwith the cones to form raceway s for antifriction' balls or bounded by the :frame rin and opposite sets of filaments "of the heaters of the spider. As shown, the blades 21 are preferably beater or ial! it mounted for movement upon the spider, and comprises a- '95. j axle sections 1'0 ,and lland' retained. thereby imperiforate and both the blades and heaters are arranged obliquely transversely of l the hub. The'beaters 22, like-the heaters 14:,

are bail or loop shape'd and are also prefer- 119 of the sections of the casing are beveled or flared inwardly toward the spider and fan, as at 23, to concentrate the charge during the process of agitation.

It will be understood from the foregoing description that the charge mixture on its flow to the engine will pass through the spider and revolve the fan, by which said.

mixture will be given a gyratory motion and its components thoroughly agitated and admixed. In this operation the fan blades will act to sweep-the mixture in a circular path and against the filaments of the stationary heaters, while the filaments of the fan will assist in such operation and coact with the stationary beating filaments to cut up and agitate the-charge into a mass of .diversely flowing streams, whereby the air and gas will be uniformly and thoroughly commhigled andany particles of 'uncommingled vaporcombined with thekair. Asa

result, a richer charge will be secured "which will insure more perfect-combustion andless liability of the failure of. ex plosion of the charge, while at the same time the-feed of vthe mixture to theengine will'be facilitated rather than retarded, thus increasingthe efliciency of motors in which the .feed of the charge mixture from the carbureter is sometimes retarded.

In the form ofmy invention shown in' Figs. 6 and 7, the casing A is composed of a. single ring having an internal central rib forming annular-shoulders 24; This ring provided with the flanges 7 like thering A whereby itmay be secured in position between the intake of theengi'ne and outlet ofthe earbureter. The spider in' this embodiment is composed of oppositely arranged an- ;nular series of radial strands or filaments 2150f; wire clamped at their outer ends against the respective shoulders 24 by annular resilient flanges 26 entering the sides of the casing and formed upon washers 2'7 clamped respectively between the intake and one side of the casing'and the-opposite side of the casingand the car-bureter inlet. I The inner ends of sajd filaments have angular bent portions 28 which are clamped between theaxle sections-29 and 30 and-the offset or fluted outer edges 30 of a pair of bearing tubes 31 held from outward {.movement said axle sections and forming the ,lioliaw tions of the tribes providing keepers in; which said angularlybent ends ofthe filaments are tightly held by the axle sections, which are flanged to prevent their lateral displacement. The tubes 28 are provided with cone surfaces between which and similar surfaces on bearingtubes 32 are interposed antifriction balls or. rollers 33, the said tubes 32forming in conjunction a separable bearing ring having annular en'd flanges 3 1, between which fits the hub 35 of the fan, which is provided with the blades 36 and bail shapcd heaters 37. These blades and heaters are arranged as in the structure shown in Figs. 1 to 5, inclusive, but are. i11 dependently for-med, each consisting of alooped portion of-wire having ungularly bent ends 38 fitting within keeper offsets or flutes 39 formed upon and extending transversely of the hub andclamped between the same and the faces andfianges of the bearing ring,

which thus forms a .complemental member of the hub aid rotates with the. body of the fan on the sectional axlev of the spider. The strands or filaments of the respective beat- .ers are arranged obliquely bybending then! at an-augle around the surface of the hub. the bent end of one filament being fitted within the end of one keeper at one side of the hub and its opposite end being fitted in the end'of the next adjacent keeper at the opposite side of the hub, as illustrated in detail in Fig. 11. This construction of mixer is designed particularly for use where sufficient space is not afforded through the intake 1 and outlet 2 for the interposition ,of

'aywider casing of the form shownin Figs. =1 to 5, 1nclus1ve, and operates in the same manner to agitate andthoroughly admix the elements of the charge.

lot

In Figs. 8, 9, 10 and 11.'I have shown still another embodimentof the invention, in which the mixer is particularly "adapted to be arranged between an engine intake and carbureter outlet where but slight spaceis afl'ordedfor its reception. As shown inthis' instance, the" casing is dispensed with and a support for the fan is rovided comprising awasher 40 adapted to be clamped bei tween the intake and outlet and provided With'integra'l lugs orifingers 41 designed'to be bent at right angles thereto and in' en-' gagernent with the wall .of the intake to assist in supporting it firmly in position.'f The washer carries a, eeifitral portion or spider consisting ofa hub 42"having an opening 43 formed therein and conneoted with the inner periphery of the washer by radial arms 44;

spaced to provide openings or passages'45 for the flowof the charged mixture." Extending through the -opening' 43 in the hub is an axlefpin 44 having a head 45' bear ing against the side of the hub facing the outlet 2' and provided beyond 'the opposite.

na htha-hub with spaced'colla'rs 6 se- I in any suitable manner thereto. The

iigsmaan this construction is mounted to re velwegupon the axle pinbetween saidcollars andjg'comprises a hub or inner bearing ring and an outer bearing ring-a8, the latter mg provided with the fan blades 49. The

I ring 48 conforms in construction with the ring 35 shown in Figs. 6 and 7, having an annular series of transversely arranged fluted keepers 50 to receive the angularly bent ends 51 of the bail-shaped heaters .52, which are constructed and applied in the I manner heretofore described with respect to plained. v .Having thus descr bed the invention, I

the heaters 37, being clamped between the inner and outer rings of the hub. The mix-' ture flows through the openings in the -spide'r'and rotates the fan, the blades of which. agitate the mixture, the component elements of which, are thoroughly commingled by the cutting action} of the fila-.

ments of the heaters, as hereinbefereweie 1.' In an air and gas mixer. for internal 'combustion. engines, a support, and a rotary member carried by said support and. provided .withan annular series of fan blades and transverse bail-shaped 'wir'es forming annular series of spaced heating filaments onthe opposite sides of saidlblades.

2. In an air and gas mixer for internal or spider carried by the support, =and'a r0 tary' member carried by the spider, said member being provided with an annular series of fan blades,and transversely arranged bail-shaped wires forming annular series of spaced beating filaments on the opposite sides of said blades.

4. In an air and gas mixer for internalcombustion engines, a support, a spider carried by the support, a plurality of stationary filaments carried by the spider, and a fan mounted to revolve upon the spider and provided with blades and Witl a plurality of beating filaments. 5. In an air and gas mixer for internal combustion engines, a support, a spider carried by the support and provided with an annular'series of looped elements, and a rotary member mounted upo'n'the spider and provided with fan blades and an annular series pf looped heaters.
